    Hi Ernest,

    Can you please ask the customer to step through the code and see where exactly it is failing?
    Also ask them to increase 'freeQ' and 'rxMsgQ' size to 50 and try it.
    Please let me know their observation after this.


    Thanks & Regards,

    H Ernest,

    I haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

    Hi Vivek,
    Sorry for late response and thank you for your consideration.

    They already did your guides but the issue still happened.
    But they solved this issue by modifying below.
    - SDK reference CAN source use 1 mailbox and receive 1 message, so they modified it to use 8 mailbox and changed msgIdentifierMask.

    Thank you.
    Best Regards,
    Ernest
